MOBI with Silicon

This is working code for developing and testing MOBI2.0 with silicon cycling (mainly from Karin Kvale) and a prognostic equation for opal.
Note of caution: this model is not tuned and has only been run for a short test run.

External sources and sinks for silicon are zero. Opal sinks with a prescribed constant velocity 'wo' and remineralizes at a constant rate.

Initial code provided by Samar Khatiwala is in the 08 updates at https://github.com/andreasschmittner/UVic2.9. You need that code to run this version (see mk.in).

mobi_silicon's Issues

Isotopes

Diatoms need to be added to the N15 and C13 equations.

Add subgrid sediment scheme to opal and CaCO3

Currently the subgrid bathymetry remineralization scheme is only used for organic matter but not for opal and CaCO3.

Si conservation

There still is a conservation issue. Si shows small increasing trend.

Si Conservation

Global Si shows a decreasing trend indicating non-conservation. Could it be due to loss to sediments?
